The Sonic Urethral Sound (SUS)

This is a vibrating/sonic sounding device I made.
Sex is the mother of invention!

I used an old Sonicare toothbrush motor (rechargeable and waterproof!)
I took the brush unit off and attached a plastic coffee stir-straw to the metal
oscillating end of the motor, then I slid a 12 inch length of vinyl tubing over that,
capped the end of the tube with silicone caulking.

Lube it up, slide it in and turn it on! The straw slaps against the
tube at 100's times per second providing an awesome senstion the
entire length of the tube.

Even better, I use either a warming micro vibe sound or the 1 inch micro vibe sound that is 3/8" in diameter, lube up, slowly push thru meatus opening and then let the slide down inside my penis while turned on. I have gotten both these into bladder and then added enemas and toys for even more pleasure. Just don't pull these out in a hurry and if you CUM, be sure to wait a few minutes , add more lube, before removing the vibe.
